Specification of Letters Patent.

Patented Sept. 26, 1916.

To all whom it may concern:

Be it known that we, CHARLES DE LUKAC- SEVICS and WVILLIAM H. DANE, citizens of the United States, residing at West Nutley and East Orange, respectively, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Siphon-Heads, of which the following is a specification.

This invention relates to improvements in siphon heads and more particularly to an improvement in the jointure of the siphon head to the bottle neck, having for its principal object to provide ameans of jointure between the siphon head and the bottle neck which shall be strong, inconspicuous, substantially gas-tight, and readily effected and which shall prevent any accidental disassociation or relative movement of the siphon head and the bottle, such as would tend to destroy or interfere with the gas-tight relation of said siphon head and bottle.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a sectional view showing an application of the siphon head to a bottle; Fig. 2 is a side elevation of the siphon head proper; Fig. 3 is a side elevation of the upper portion of the bottle and showing more particularly the details of the bottle neck; Fig. 1 is a top plan view of the bottle; and Fig. 5 is an elevation of the siphon head applied to a bottle. Y

Similar characters of reference designate corresponding parts throughout the several views. I

The bottle, as A, has its neck provided with an upper reduced portion 1 formed with relatively steep and preferably rounded external threads 2 which terminate adjacent the upper end of said neck and ex tend from a point adjacent an annular flat shoulder 3 formed, by virtue of the provision of the reduced neck portion 1, adjacent the lower end of the same.

The siphon head has its lower portion formed as a socket 4 to engage over the bottle neck and provided .with internal threads 5 for engagement with the threads 2. A gasket 6 is preferably interposed between the upper face of the bottle neck and the base of the socket. The socket i has a sired form. In Fig. 1 they are shown as of'semi-circular form, in Figs. 2 and 3 as of V-shape form, and in Fig. 5 as of halfsquare form.

The extent and relation of the threads 2 and 5 are so selected that when the socket is screwed down upon the bottle neck sufiiciently to exert sealing pressure upon the gasket 6, anannular space 9 will be left between the face 7 and the shoulder 3 and the grooves 8, the intervals of which are the same in both of the confronting faces, will preferably be in registry, or substantially so. Lead in a soft or plastic state or some other equivalent agency is thereupon poured into the. space 9 until it completely fills the same and the registering grooves 8 which openinto said space. The lead filling when it hardens forms an annular sealing key 10 between the under face of the socket 4 and the shoulder 3 and .by virtue of the provision of the grooves 8 takes a form wherein it vprovides radial locking ribs 11 which have secure engagement in said grooves and which, of course, extend across the space 9 and are integral with the major or body portion of the key 10 which has sealing engagement in said space 9. When the lead sealing key- 10 with its locking ribs 11 has set, a gas-tight jointure is established between the under face of the siphon head and the bottle neck and the eficiency ofthis j ointure is permanently maintained since the ribs 11 prevent any relative turning movement of the siphon head and the bottle neck such as would tend to interfere with the seal established by the gaskets 6 and 10.

The j ointure between'the siphon head and the bottle neck is advantageous, from the standpoint of appearance, in that it is neat andinconspicuous and it is further advantageous in that the lead key does not project beyond the adjacent faces of the siphon head and bottle neck but is substantially flush therewith and, hence, being unexposed, is not liable to intentional or accidental injury and presents no temptations to persons of destructive tendencies.

WVhile the locking and sealing key 10 effectively holds the siphon head against movement, and as just explained, is so arranged that it is not liable to intentional or accidental injury, said key may be readily removed by an authorized person whenever the occasion may require.

Having fully described our invention, we claim 1. In combination, a bottle having a threaded neck portion, a siphon head having a threaded portion to engage said neck portion, the bottle having a shoulder and the siphon head having a flat face confronting said shoulder, said shoulder and flat face having radial grooves and a locking and sealing element filling the space between said shoulder and said flat face and also filling said grooves.

2. In combination, a bottle having a threaded neck portion, a siphon head having a threaded portion to engage said neck portion, the bottle having a shoulder and the siphon head having a fiat face confronting said shoulder, said shoulder and flat face having radial grooves and a locking and sealing metal key cast in the space between said shoulder and said flat face and extend ing into and filling said grooves.

8. In combination, a bottle having a threaded neck portion, a siphon head having a threaded portion to engage said neck portion, the bottle and the siphon head having confronting faces arranged in upper and lower relation and provided with grooves, and a sealing element filling the space between said confronting faces and also filling said grooves.

4. In combination, a bottle having a threaded neck portion, a siphon head having a threaded portion to engage said neck portion, the bottle and the siphon head having confronting faces arranged in upper and lower relation and provided with grooves, and a locking and sealing metal key cast in the space between said confronting faces and filling said grooves.

5. In combination, a bottle having the upper portion of its neck reduced and provided with external threads and having an annular external shoulder adjacent the base of said threads, a siphon head having an internally threaded socket to engage upon said threaded neck portion, the under face of said socket confronting said shoulder, a gasket interposed between the base of said socket and the upper end of the reduced neck portion, the under face of said socket and said shoulder being provided with radial grooves, and alocking and sealing element filling the space between said shoulder and the under face of said socket and also filling said grooves.

6. In combination, a bottle having the up per portion of its neck reduced and provided with external threads and having an annular external shoulder adjacent the base of said threads, a siphon head having an internally threaded socket to engage upon said threaded neck portion, the under face of said socket confronting said shoulder, a gasket interposed between the base of said. socket and the upper end of the reduced neck portion, the under face of said socket and said shoulder being provided with radial grooves, and a locking and sealing metal key cast in the space between said shoulder and the under face of said socket and extending into and filling said grooves.

7. In combination, a bottle having the upper portion of its neck reduced and provided with external threads and having an annular external shoulder adjacent the base of said threads, a siphon head having an internally threaded socket to engage upon said threaded neck portion, the under face of said socket confronting said shoulder, the under face of said socket and said shoulder being provided with radial grooves, and a locking and sealing element filling the space between said shoulder and the under face of said socket and also filling said grooves, said element being flush with the adjacent external faces of said siphon head and said bottle.
